Living over 200 years before the beginning of the series, Aeolia Schenberg establishes the theoretical basis of the combined orbital elevator and photovoltaic energy system, the construction and defense of which he foresaw to employ humanoid machines not unlike mobile suits.[e 1] In a long term plan to rid the world of armed conflict and ready humanity for the next phase of its evolution, Aeolia founds the private paramilitary organization Celestial Being and develops the technology behind the GN Drives.[e 2] It is this plan that becomes the driving force for both the first and second series. Schenberg's body is held in cryogenic stasis within Veda, intending to awaken when the world is rid of conflict. However, soon after this discovery near the end of the first series, Alejandro Corner kills Schenberg in order to take over the plan, however Schenberg's death triggers a system trap that activates the Trans-Am System in the four Gundams and unlocks the secrets behind the Twin Drive System.[e 3] Aeolia Schenberg is voiced by Chikao Ōtsuka (TV series) and Tsutomu Isobe (Movie) in Japanese and Michael Kopsa in English.

A celebrity of Chinese descent, whose name is well known in the high society of the world, and is one of the secret agents of Celestial Being. She uses her wide social connections to conduct espionage activities and fund raising, passing mission details to the Gundam Meisters supporting Ptolemaios from the shadows. She wishes for the world to change so she can reinvent herself, begrudging her role as her family's head, a position she inherited when she was fifteen. Willing to sacrifice anyone to achieve that goal, she would rather the world be destroyed if it cannot change. In the second season, Liu Mei is shown to be supporting both Celestial Being and the Innovators effectively playing both sides until Ribbons has no more need of her. Forming an alliance with Regene, Liu Mei hands Setsuna the coordinates that reveal Veda's location, only to be later killed by Nena Trinity as she attempts to leave the battle field. Wang Liu Mei is voiced by Kei Shindo in Japanese and Maryke Hendrikse in English.

Wang Liu Mei's steward and bodyguard also of Chinese descent, who accompanies her faithfully. A highly skilled martial artist, he is also Liu Mei's older half-brother.[e 4] Because he was incapable of leading their family, Liu Mei was forced to become the head of their family; as a result, she resents her brother for his behavior. As one of Celestial Being's agents, Long assisted Setsuna and Lockon during their mission in Azadistan.[e 5] In the second season, Long questions Liu Mei about 'playing both sides', since it could result in the destruction of the Gundams. He and Liu Mei manage to survive after Nena Trinity's attacks on their ship [e 6] in the Throne Drei.[e 7] However, as they make their way into a satellite, Nena ambushes them; Hong Long pushes his sister into a seal-docking port as he sacrifices himself to save her, killed with a shot to the head. Hong Long is voiced by Kenji Takahashi in Japanese and Samuel Vincent in English.

The series focuses on the four mobile suit pilots of the paramilitary organization Celestial Being. The pilots, referred to as Gundam Meisters (マイスター,Maisuta?, German for Master), pursue the complete eradication of armed conflict mainly through the deployment of the revolutionary Gundam units in aggressive armed interventions.

Setsuna F. Seiei is the primary protagonist of the series and was discovered by Celestial Being at the age of 16 for having special potential as a pilot. He is currently a Gundam Meister and pilots Gundam Exia, specialized in melee combat. Setsuna's real name is Soran Ibrahim (سوران إبراهيمSuran Ibrahim); with Setsuna being his codename. He was once a child soldier of Kurdish descent in the war-torn Krugis Republic.[e 2] During this time, he murdered his own parents under Ali Al-Saachez's influence in order to prove his devotion to God,[e 8] and hence bears a deep hatred towards Saachez. Due to his previous religious brainwashing (and awakening from it), Setsuna claims he no longer believes in God, yet still debates the role of God in people's lives, suggesting that he would like to believe in God. After going into hiding at the end of the first season, Setsuna reappears four years later and rejoins Celestial Being as the pilot of 00 Gundam during his fight with the Innovators and then 00 QAN[T] during his battle with the ELS. Disappearing at the later fight, Setsuna reappears decades later. Throughout the series he had a potential love interest with Marina Ismail. Their feelings for each other remain unclear, but it is of no doubt that they truly cared about each other, as he meets her after returning from his mission in the ELS world.Feldt Grace was another potential interest, but it was more on Feldt's side of admiration for him. Setsuna F Seiei is voiced by Mamoru Miyano and Yuka Nishigaki (child) in Japanese and Brad Swaile in English.

Neil Dylandy is the first Lockon Stratos who decided to join Celestial Being because his parents and younger sister were killed in a terrorist bombing. As the eldest pilot, he is considered the pilots' team leader, and sports a more easy-going, flamboyant personality as compared to the other Gundam Meisters. He owns an orange Haro to help pilot the Gundam Dynames and has a personal feud with Ali Al-Saachez, who plotted the terrorist bombing that caused the death of his family.[e 9] After being killed at the climax of the first season, his younger twin brother Lyle Dylandy chooses to take up the title of Lockon Stratos and becomes the pilot of the Cherudim Gundam. Neil Dylandy is voiced by Shinichiro Miki in Japanese and Alex Zahara in English.

First seen in episode 9 of the first season, he was visiting the grave site of his family. Four years after the death of Neil Dylandy, Setsuna F Seiei recruits Neil's twin brother, Lyle, to become the new Lockon Stratos and pilot of the Cherudim Gundam and then Zabanya. He is shown to be easy-going like his brother, but continues to struggle with distinguishing himself from Neil. He becomes romantically interested in the Innovator Anew Returner until she is killed by Setsuna, of which Lyle violently beats Setsuna for. Originally a double agent from the anti-government organization Katharon, Lyle leaves Katharon and becomes a full-time member of Celestial Being at the end of the second season. During the events of the movie, Lyle pilots Gundam Zabanya during the fight with the ELS. Lyle Dylandy is voiced by Shinichiro Miki in Japanese and Alex Zahara in English.

Allelujah Haptism spent his childhood as an orphan in the Human Reform League as a Super Soldier experimental subject in a supersoldier project, designated "E-57". While generally gentle and rational compared to the other Gundam Meisters, the experiments and drama of killing his fellow subjects in order to survive when their escape went array caused him to manifest a second personality in the form of Hallelujah(ハレルヤ,Hareruya?), a bloodthirsty and outright sadistic personality. He is the pilot of Gundam Kyrios and Gundam Arios, as well as one of the pilots of Gundam Harute; all of which specialize in high mobility and are able to transform into fighter jets. Allelujah's rival in combat is another subject of the Super Soldier program, Soma Peries whom he shared deep connection which Hallelujah realized long before he did.[e 10] Though Allelujah managed to reach common ground with his alter ego to reach his full potential as a super soldier, Halelujah "died" revealing Soma's identity as Marie Parfacy before he is captured and imprisoned during the four-year time-skip between both seasons but ends up being rescued by his companions after the other three Meisters reunite. In the process, after Soma reverts to Marie, Allelujah convinces her to join Celestial Being with the two becoming allies. But during moments whenever 00 Raiser's Trans-Am System, the Hallelujah persona resurfaces. In the series aftermath, Allelujah and Marie have apparently left Celestial Being to find their place in the world. During the events of the movie, Allelujah and Marie rejoin Celestial Being to fight the ELS in Gundam Harute. Allelujah Haptism is voiced by Hiroyuki Yoshino and Masako Jou (child) in Japanese and Richard Ian Cox in English.

Gundam Meister of the heavily armored Gundam Virtue/Nadleeh, its successor unit Gundam Seravee/Seraphim and finally Gundam Raphael. Tieria Erde treats Veda's orders with high regard, valuing the mission above all other issues. As a result of his arrogance and cold attitude towards others, his relationship with the other Gundam Meisters got off a rocky start. However, his attitude towards the other Meisters and the Ptolemaios crew gradually improves after being protected by Lockon Stratos from an attack in a battle against the AEU and Union, an action which costs Lockon the use of his dominant eye. Of all the Gundam Meisters, Tieria is the most enigmatic, with an unknown past and a peculiar connection with the Innovators.[1] Contrary of the other Meisters who were either K.I.A. or M.I.A. in the end of the first season, Tieria continued to work for Celestial Being during the 4-year time-skip. At the end of the second season, Tieria is killed by Ribbons Almark while trying to stop him from taking control of Veda. Tieria however manages to upload his consciousness into Veda itself, subsequently ending the battle by remote-controlling Seraphim from Veda's core and activating its Trial System to shut down all enemy mobile suits. He briefly returns in the movie in a new body and pilots Gundam Raphael briefly before sacrificing himself to save Setsuna, but he eventually ends up uploaded into Setsuna's 00 Qan[T] and is last seen when the Gundam departs to the ELS homeworld. His fate is unknown, although the 00 Qan[T] returns to Earth in the epilogue and a Tieria-type Innovade briefly appears aboard the Sumeragi. Tieria Erde is voiced by Hiroshi Kamiya in Japanese and Samuel Vincent in English.

Supporting the Gundam Meisters is the crew of the Ptolemaios(プトレマイオス,Putoremaiosu?) led by Sumeragi Lee Noriega. At the end of the first season, the Ptolemaios was severely damaged and many of its crew were killed. During the second season, the new Ptolemaios II enters service crewed by the surviving members of the original Ptolemaios. They are later joined by Saji Crossroad and Soma Peries, the latter after recovering her memory as Marie Parfacy.

Sumeragi is the tactical forecaster of the Celestial Being mothership Ptolemaios. As the most senior ranking officer on the ship, she is the de facto captain of the ship. She plans all the strategies the Gundam Meisters take part in and her strategic predictions are almost always accurate. Her real name is Leesa Kujo. In the beginning of the second season, Sumeragi is reluctant to rejoin the others until the encouragement from her companions helps her find the resolve to help them. At the end of the series, she remains with Celestial Being. Sumeragi Lee Noriega is voiced by Yōko Honna in Japanese and Lisa Ann Beley in English.

Feldt is the daughter of Ruido Resonance and Marlene Vlady, who initially worked under Celestial Being as Meisters for the 2nd-generation GNY-series Gundam prototypes and later got married. In the beginning of the series, Feldt works as the tactical operator of Ptolemaios and later the Ptolemaios 2. In addition to her programming skills, Feldt is also a capable mechanic. Though she tends to be reserved, she feels strongly towards all the members of Celestial Being as her family. She is strongly implied to have had a crush on Neil Dylandy until the latter's death but between the end of the second season and the movie, she openly develops romantic feelings for Setsuna. Feldt Grace is voiced by Ayahi Takagaki in Japanese and Chantal Strand in English.

Christina Sierra is the Ptolemaios tactical operator. Christina ran away from her adopted mother before being discovered by Celestial Being. She becomes good friends with fellow crewmate Feldt. During the battle at Lagrange point 1, the bridge of Ptolemaios is attacked by a GN-X. Although Lichtendahl Tsery shielded her from the attack, she is fatally wounded by a shred of metal from the shattered bridge. Before Lichty dies in her arms, she realizes her own feelings for him. She contacts the surviving crewmembers and tells Feldt to live on for Lockon's memory, before dying in the subsequent explosion.[e 11] Christina Sierra is voiced by Arise Satō in Japanese and Shannon Chan-Kent in English.

Lichtendahl Tsery, called Lichty by his fellow crewmates, is the Ptolemaioshelmsman. Lichty's parents were technicians on one of the orbital elevators and killed during the Solar Wars while he lost a large portion of his body, which was replaced with machinery. Although Lichty has a romantic interest in crewmate Christina, she maintains a friendly and professional relationship. During the battle at Lagrange point 1, the bridge of Ptolemaios is attacked by a GN-X, Lichty is fatally wounded while shielding Christina from the explosion. He soon dies in Christina's arms after she realizes her own feelings for him.[e 11] Lichtendahl Tsery is voiced by Masataka Azuma in Japanese and David A. Kaye in English.

Initially, Lasse served as the gunner for the Celestial Being mothership Ptolemaios. He also piloted the GNR-001 GN Arms, a transformable weapon docking system for the four Gundams. In the final battle with the UN forces, Lasse helps Setsuna fight Alejandro Corner in the Alvatore/Alvaaron; though he survives the battle, his health suffers from overexposure to Fake GN particles. In the second season, he serves as the Ptolemaios II's main helmsman but during the season's final battle he briefly pilots the 0 Gundam until it runs out of power. At the end of the season, Lasse remains part of Celestial Being. Lasse Aeon is voiced by Hiroki Touchi in Japanese and Andrew Francis in English.

Joyce Moreno is the Ptolemaios doctor and longtime friend of fellow crewmate Ian Vashti from before both joined Celestial Being. Fifteen years earlier, he was a member of Doctors without Borders and began referring to himself as "JB Moreno."[2] He is killed when the Alvatore fires upon the Ptolemaios and destroys the medical bay.[e 11] Joyce Moreno is voiced by Go Shinomiya in Japanese and Brian Drummond in English.

Ian Vashti is the head of Celestial Being's mobile suit development along with his wife and daughter. On the Ptolemaios, Ian works as the ship's main engineer. He is a kind hearted man but gets angry when his machines are damaged. Ian Vashti is voiced by Hideyuki Umezu in Japanese and Peter New in English.

Mileina Vashti is Ian's and Linda's daughter who joins the crew of the Ptolemaios II before the beginning of the second season. Despite her young age, she is a gifted technician, learning much about engineering, GN Technology, and programming from both her parents. Mileina normally staffs the tactical operations station, but she also helps her father as a mechanic, and even temporarily takes over his role when he heads to Celestial Being's L3 base ahead of the Ptolemaios II. In the movie, she openly declares love to Tieria just prior to the latter leaving for the final battle and subsequently the ELS homeworld; it's unknown if they develop a relationship or not. Mileina Vashti is voiced by Haruka Tomatsu in Japanese and Andrea Libman in English.

Linda Vashti is Ian's wife, and mother to Mileina. She appears in the background of episode 2 in the second season, but does not make a proper appearance until Ian later travels to space in episode 9 to retrieve the 0 Raiser. Linda later delivers supplies, new equipment for the Gundams and the 0 Gundam to Ptolemaios II and joins Ian in the weapons control room. Linda is noticeably younger than her husband. Linda Vashti is voiced by Risa Hayamizu in Japanese and Jillian Michaels in English.

The Gundam Meisters and the crew of the Ptolemaios face many opponents from the three major powers, the Union, Human Reform League, and AEU during their armed interventions in the first series. In the second series, the Gundam Meisters find opposition in the form of new and returning enemies during their battle against the Earth Sphere Federation's A-Laws and the Innovators.

The World Economic Union(世界経済連合,Sekai Keizai Rengō?, abbrev. Union(ユニオン,Yunion?)), also referred to as the Union of Solar Energy and Free Nations(太陽エネルギーと自由国家連合軍,Taiyō Enerugī to Jiyū Kokka Rengōgun?), is a supranational politico-economic community consisting of the Organization of American States, Australasia, and Japan. It controls the first-completed of the three orbital elevators, located in South America.

Graham Aker is an antagonist of the series and is often considered the archrival of Setsuna F Seiei. Prior to the series, he joined the military to live his dream of flying and became an ace pilot. However, a freak accident resulting in the death of a superior officer and his sudden promotion made Graham a victim of rumors. When Celestial Being makes its appearance in the world, Graham is promoted to Captain of the Over Flags. Though he originally had a love for the Gundams, the actions of Team Trinity causes Graham's feelings to exceed into utter hatred. In the final moments of Operation Fallen Angels, Graham uses the GN Flag to attack Setsuna, exchanging blows and clashing ideals with him before the battle ends with Graham receiving scars on the right side of his face. Four years later, Graham dons a mask to cover the scars and becomes a member of the newly formed A-Laws under the alias of Mr. Bushido(ミスター・ブシドー,Misutā Bushidō?). Possessing a one-man army pass, Graham was given special permission to do as he wishes during battles, preferring to battle Setsuna.[e 12] Graham is the Union's ace pilot and follows a strict code of honor. With a skill unmatched by any Flag pilot, Graham is eager to find an opponent worthy to fight. When Gundam Exia first appeared in the AEU exhibition and destroyed their new unit, the Enact, he grew completely interested in the Gundam's capabilities, as Billy Katagiri notes, he's "quite infatuated" with the Gundams. After losing to Setsuna, who spared him, Graham takes Setsuna's words to live to heart while he is contemplating seppuku. In the end of series, he is standing back of door watching Billy work.[e 13] In the Gundam 00 Movie, he sacrifices himself to help Setsuna to get in to the ELS core. Graham Aker is voiced by Yuichi Nakamura in Japanese and Paul Dobson in English.

Billy Katagiri is a mobile suit developer and friend of Union ace Graham Aker. After the appearance of Celestial Being, Billy, Graham, and Professor Ralph Eifman, who had taught Billy in college, are transferred to the Anti-Gundam Investigative Task Force, later named "Overflags".[e 14] Billy is a former classmate of Leesa Kujo (aka Sumeragi Lee Noriega) and inadvertently leaks information about "Project G" to her and Celestial Being.[e 15] After the death of Professor Eifman and Howard Mason during an attack by Team Trinity,[e 16] Billy uses one of the recently acquired GN Drives to upgrade Graham's Flag unit to the GN-Flag in order to fight the Gundams.

By the second season, Billy is taking care of a despondent Kujo, still unaware that she was a member of Celestial Being until Setsuna F Seiei appears to retrieve her.[e 17] Shocked by this revelation and feeling betrayed, Billy joins the A-Laws and becomes the head of mobile suit development. Once again teaming up with Graham Aker, now using the alias Mr. Bushido, Billy develops the Masurao and the upgraded Susanoo. Billy disappears after the collapse of the African orbital elevator, but reappears four months later to provide his Trans-Am findings to the Innovators as he personally confronts Kujo while claiming to embraced the Innovators' ideals of world peace. However when exposed to the 00 Raiser's Trans-Am, Billy is forced to expressed his feeling to Kujo as she apologized for hurting him.[e 12] In the ending of series, a picture of him and Kujo shown in front of desk when Billy himself smile looking his picture doing his work while Graham standing on back watching him [e 13] Billy Katagiri is voiced by Yūji Ueda in Japanese and Kirby Morrow in English.

A Union NCO with the rank of Warrant Officer. One of the first Flag Fighters assigned to the Anti-Gundam Investigative Task Force "Overflags" under Graham Aker. He seemed to have a friendship with Graham due to their belief in the qualities of the Flag. He has brown hair and glasses. He was killed in action by Michael Trinity. After his death, Graham and Daryl vowed to avenge his death. Howard Mason is voiced by Kenji Takahashi in Japanese and Trevor Devall in English.

A Union soldier with the rank of Master Sergeant. Another of the first Flag Fighters assigned to the Anti-Gundam Investigative Task Force "Overflags" under Graham Aker. Unlike Graham and Howard, he doesn't share their faith that a Flag can beat the Gundams. He is transferred to the Union's GN-X squad where he meets Patrick Colasour and tells him not to badmouth Graham. He is killed after performing a head-on suicide attack on Gundam Dynames in order to avenge Howard Mason's death. Daryl Dodge is voiced by Rintarou Nishi in Japanese and Scott McNeil in English.

A world famous Union professor who is invited to join the Overflags as their technical chief. He taught both Sumeragi Lee Noriega and Billy Katagiri in college and knows them both well. When Graham asks him whether the Gundams' action may bring the world to an end, Eifman does not deny the fact. Professor Eifman joined the Union's Anti-Gundam Investigative Squad as their technical chief and adviser to aid in capturing the Gundams. Having Billy at his side, they custom modified Graham Aker's Flag and renamed it as "Over Flag." Eventually these modifications were expanded to an entire squadron of Over Flags to stand against the Gundams. While doing his investigation regarding Celestial Being, Eifman was on the verge of a major revelation about their ultimate intention but was killed by Team Trinity. Ralph Eifman is voiced by Takaya Hashi in Japanese and Ron Halder in English.

The Human Reform League(人類革新連盟,Jinrui Kakushin Renmei?, abbrev. 人革連 Jinkakuren, lit. Human Reform Alliance) is a supranational political-economic community consisting of several countries on the Asian continent which includes China, India, Russia and the ASEAN nations. It controls the second-completed of the three orbital elevators located in the South Pacific.

Sergei Smirnov is a colonel and mobile suit squadron commander of the Human Reform League to capture the Gundams. He is a respected man who follow orders without question and shows true dedication on his missions in spite of doubt. He served as a father figure to Soma when she was assigned to him, offering to adopt her. But when he finds Soma with Allelujah, he lets her join Celestial Being and falsely reports Soma as KIA. Doubting the motives of the A-Laws, Sergei learns his old friend Hank Hercule is attempting a coup d'etat. Though secretly sent by the government to give him their demands, Sergei is killed by his son, Andrei, who assumed that he was part of the coup de'etat. Sergei Smirnov is voiced by Unshō Ishizuka in Japanese and Michael Dobson in English.

Soma Peries is a super soldier from the Human Reform League. Originally Marie Parfacy(マリー・パーファシー,Marī Pāfashī?), she was an orphaned test subject who lost her physical senses due to psychosomatic paralysis. She was befriended by Allelujah before he and the other flawed subjects escape. Once put through the latter stages of her supersoldier treatment, Marie's personality was rewritten and become Soma Peries. At her first appearance, Soma pilots the MSJ-06 II-SP Tieren Taozi, and later a GNX-603T GN-X unit. During the first season, she targeted the Kyrios' pilot as a traitor, unaware he is Allelujah, while viewing Sergei as a father figure over time. While drafted into the A-Laws during season 2, Soma is given the customized GNX-704T/SP Ahead Smultron. However, while confronting Allelujah, Soma regains her original identity of Marie as they put the past behind them. As a member of Celestial Being, she eventually pilots the GNR-101A GN Archer. When Sergei is killed by Andrei, Marie's personality reverts to being Soma until the end of the final battle. In the series aftermath, she and Allelujah have apparently left Celestial Being and are finding their place in the world. Soma Peries is voiced by Arisa Ogasawara in Japanese and Tabitha St. Germain in English.

The Advanced European Union(新ヨーロッパ共同体,Shin Yōroppa Kyōdō-tai?), or AEU, is a supranational politico-economic community consisting of Iceland, the islands of the Barents Sea, Greenland, Anatolia, European Russia and the entirety of the traditional continent of Europe. Its institutional makeup is comparable to that of the real-world European Union. Despite the AEU's control of the presently incomplete orbital elevator tower in Africa, it possesses no member states on the continent.

Patrick Colasour is an ace pilot of the AEU and the first to be confronted by a Gundam during a public demonstration of the AEU's new Enact mobile suit. Although the Enact was completely destroyed by Gundam Exia, Patrick survives with only his ego wounded.[e 2] Patrick's subsequent encounters with the Gundams do not fare any better, although he manages to wound Gundam Dynames's pilot, Lockon Stratos, while Lockon shields a disabled Gundam Virtue, piloted by Tieria Erde, from Patrick's attack.[e 18]

During the preparations for "Project G", a joint military operation between all 3 power blocs, Patrick meets Kati Mannequin for the first time and—after she punches him twice for being late—claims to have instantly fallen in love with her.[e 15] In the second season, Patrick joins the A-Laws to be with Mannequin against her wishes. Because he has survived all his encounters with the Gundams, he gains the nickname "Colasour the Indestructible" (不死みのコーラサワ,Fujimi no Colasour?, lit. "Immortal Colasour"), though it is meant as an insult.[e 19] After the collapse of the African orbital elevator, Patrick goes missing along with Mannequin, but reappears four months later having joined the coup d'etat fleet that attacks an A-Laws fleet near L2.[e 20] While aiding the Gundams, Patrick is caught off guard when the Innovators' Gaga units appear and his mobile suit is destroyed while shielding Mannequin's ship.[e 12] He survives the blast and later marries his beloved Kati, self-proclaiming himself as "Colasour the Ridiculously Lucky" (幸せのコーラサワ,Shiawase no Colasour?, lit.Fortunate Colasour).[e 13] Patrick Colasour is voiced by Kenji Hamada in Japanese and Trevor Devall in English.

Kati Mannequin is a Colonel in the unified AEU armed forces. She attended the same international university as Leesa Kujō and both were involved with unintentionally causing a friendly fire incident to occur that led to them on opposing sides when Celestial Being appears. Selected to be the commanding officer of the AEU contingent sent to the HRL's Taklamakan Desert, Kati attempts to capture a Gundam unit. Kati is later assigned command of the joint Union-AEU battle group consisting of GN-Xs in conjunction with the HRL's Sergei Smirnov. Five years later, Kati Mannequin joins A-laws to help Sergei monitor the organization's activities; as a commander for the A-laws, she realizes that Leesa Kujō is the tactical forecaster for Celestial Being. Though she eventually goes against the A-Laws, Kati still sees Celestial Being as a terrorist group and will not hestiate to pursue if forced to. Kati Mannequin is voiced by Minami Takayama in Japanese and Cathy Weseluck in English.

Ali Al-Saachez (علي الساجيسAli al-Sajis) is a major antagonist of the series, and the former cell leader of the KPSA terrorist group in which Setsuna was a former member. Generally a sadistic sociopath, Ali merely fights to appease his insatiable appetite for conflict and destruction, adapting various aliases to work for any party that feeds his desire for more conflict. In spite of his brutish nature, Ali has proven himself to be an extremely skilled tactician with fighting abilities that border on being superhuman, and routinely fights the Gundams to a standstill before gaining his own advantage. Eventually, he manages to steal the Gundam Throne Zwei while killing two of the three Trinity Siblings. However the machine is soon destroyed after Ali's fight with Neil Dylandy. Barely surviving with most of his body damaged, Ali managed to recover and now works for the Innovators, piloting the Arche Gundam. He is killed by Lyle Dylandy in episode 24 of season 2. Ali Al-Saachez is voiced by Keiji Fujiwara in Japanese and Scott McNeil in English.

Alejandro Corner is the main antagonist of the series' first season. Originally an observer of Celestial Being assisted by Ribbons, supporting them from the shadows, Alejandro doubles as a diplomat of the United Nations. However, Alejandro and his family had ulterior motives in supporting Celestial Being in controlling the world they create. As a result, he committed sabotage against Celestial Being to gain control of Veda. But after Veda shuts its most precious data to him, Alejandro pilots the GNMA-XCVII Alvatore and then the GNMS-XCVII Alvaaron to eliminate Celestial Being. He is killed after his Alvaaron explodes during the battle with Exia, spending his final moments discovering that Ribbons had used him as a pawn the entire time. Alejandro Corner is voiced by Yasunori Matsumoto in Japanese and Andrew Kavadas in English.

The Autonomous Peace-Keeping Force, or A-Laws(アロウズ,Arōzu?), is the primary antagonistic organization of the second series. Officially, their mission is to further unify nations by rooting out anti-government resistance. But their ideals and tactics are a facade of brutal oppression. Their actions trigger the emergence of some anti-Federation forces, like Katharon, and Celestial Being, which returns after four years. Many characters from the first series join the A-Laws, including Graham Aker (as Mr. Bushido), Billy Katagiri, Soma Peries, Patrick Colasour, Kati Mannequin and Louise Halevy.

Andrei Smirnov is the estranged son of Sergei Smirnov and member of the A-Laws. Andrei holds a grudge against his father for not protecting his mother 14 years before the beginning of the second season and joins the HRL military and later the A-Laws to forge his own path. Andrei meets Louise Halevy and develops a relationship as he sees her more suited as a lady then a soldier, often protecting her in battle. After the AEU's orbital elevator collapse as a result of a coup d'état by the Federation's military, Andrei kills his father in a fit of rage when Andrei assumes that Sergei sided with the coup d'état forces. He eventually comes to terms with his father's actions and in the epilogue, continues to serve in the Federation army in relief efforts in order to live up to his mother and father's hopes for the world. In the Gundam 00 Movie, Andrei battled against the ELS with his after the ELS threatened the well-being of mankind. In the final battle, he fights valiantly against an ELS GNX-IV and defeats the enemy, but the right arm of his GNX-IV is assimilated along with his beam rifle. He uses his GN Buster Sword to cut off the arm, and discovers an ELS carrier heading towards Earth. Activating Trans-Am, he slices the carrier a few times before a part of his suit is assimilated. He, along with a few of his comrades in GNX-IVs, then proceed to overload their GN Drive Taus with Trans-Am, and destroy the ELS carrier along with themselves and their MSs. Before his death, he sees his parents, and yells “I am a soldier, I will protect the civilians!" Andrei Smirnov is voiced by Tetsu Shiratori in Japanese and Brent Miller in English.

A former member of the Union army and Captain of his own platoon, Barack pilots the newly developed GNX-704T Ahead and is responsible for the extermination of anti-government forces, mostly Katharon. His wife was killed shortly before the commencement of the second season after being involved in one of Katharon's anti-Federation terrorist attacks. Initially looking down on Louise Halevy, Barack often shows a great concern for her due to her young age, often chastising her for her reckless behaviour on the battlefield. He is eventually killed by Setsuna after the 00 Gundam docks with the 0-Raiser, and is later promoted posthumously to Lieutenant Colonel. His passing causes a significant amount of grief in Louise. Barack Zinin is voiced by Tetsu Inada in Japanese and Mark Gibbon in English.

A fat man with curly blond hair who holds a high position within the A-Laws. He initially appears in the epilogue of the first season, next to Kati Mannequin in the Federation lineup, but is not introduced proper until second season. He overlooks the A-Laws' operation against Katharon, and is highly interested in Barrack's and Louise's encounter with Gundams Exia and Seravee, stating that "more equipment" is required. He is later seen in a conversation with Kati Manneqin and Arba Lindt. After Lindt's defeat to Celestial Being, Arthur orders that the command be given back to Kati Manneqin, telling them that failure is unacceptable in A-Laws. He is one of the A-Laws officers present in the A-Laws party. He is later seen leading the operations to obliterate the Suille Kingdom, destroy the Africa Tower along with the coup d'etat forces, and attack Celestial Being using the Memento Mori weapons. He is also seen at the speech of the ESF President, and later after the operation in episode 19 to wipe out the Gundams and the Ptolemaios II, mocking Healing Care for her failure to carry out the operation, and also decrying the decision to give her and Revive licenses. His assault, however, fails due to an uprising led by Kati Mannequin aiding Celestial Being and Katharon, with Setsuna killing Goodman. Arthur Goodman is voiced by Hisao Egawa in Japanese and Jason Simpson in English.

The uncle of Union member Billy Katagiri. He is the commander of the A-Laws. He also has a secret connection with the Innovators. When his nephew, Billy, is recruited into the A-Laws, he installs him as an MS Technical Chief and tells him that he has high hopes in him. When the 00 Gundam destroys the ship led by Lee Zhejiang to stop the Ptolemaios II from escaping to space, Commander Katagiri reluctantly decides to accept the aid of the Innovators in order to defeat Celestial Being and prevent further sacrifices. The Innovators soon deployed in the A-Laws as licensed officers, with new, powerful suits to combat the Gundams.

After the Ptolemaios II destroys the superweapon Memento Mori, the Federation government grants the A-Laws direct control of the military to further increase security. However, Homer fears that public support will eventually go to the anti-government force, Katharon and tasks Brigadier General Arthur Goodman to handle Celestial Being. His fears later realized when a number of dissidents in the regular army, led by Colonel Hank Hercule, occupied the AEU's orbital elevator. Worried that Katharon activities will increase, Homer orders Commander Kim in the regular army to send Sergei Smirnov on a top secret mission to ask the dissidents to surrender. When negotiations fail, Commander Katagiri sends Goodman into space to use another Memento Mori to completely destroy the elevator. At the end of the season, after news of the A-Laws disbanding was broadcast, Homer commits seppuku rather than facing charges. Homer Katagiri is voiced by Ryūzaburō Ōtomo in Japanese and Brian Drummond in English.

A man with a slightly wrinkled face and a head of grey hair, he is shown to be arrogant and overconfident in his abilities. Kati Mannequin recognizes that he is known for search and destroy type operations. He commands the attack on the Celestial Being flagship, Ptolemaios II, but his strategy was thwarted by Celestial Being's tactical forecaster, Sumeragi Lee Noriega. He and his crew would have been killed by the 00 Gundam, if not for the timely arrival of Mr. Bushido. After his defeat and the loss of Trilobite, he is forced to give command to Kati Mannequin. When the A-Laws headquarters decide to attack the Katharon base with the automatons, he simply tells Kati that there is no need to feel sympathy for them. After Soma is declared KIA, he gives the Ahead Smultron to Louise Halevy. During the strategy planning, he prepares a squad to follow his plan, but Kati Mannequin changes part of it. He is among the A-Laws members who lead the Memento Mori operation. Lindt is killed after the ship under his command is caught in the explosion of Momento Mori. Arba Lindt is voiced by Kazuki Yao in Japanese and Andrew Toth in English.

The Innovators (Innovades) as they appear in season 2. From left to right: Regene Regetta, Hiling Care, Ribbons Almark, Divine Nova, Bring Stabity, and Revive Revival

At the start of Celestial Being's armed intervention, Ribbons Almark, from behind the scenes, leads a group consisting of six individuals known as Innovades(イノベイド,Inobeido?), beings created by Aeolia Schenberg to pose as Innovators(イノベイター,Inobeitā?). Supposedly essential to Aeolia's plan, Ribbons claims that they are "the future of mankind" while they are actually impressions of the true Innovators that would manifest within humans. Considered to be existences that surpass normal humans, they are beings created through means of heavy gene manipulation and nanotechnology. They are characterized by their advanced ability to use quantum brainwaves and directly interface with Veda, as well as their agelessness and androgyny. Tieria Erde is also an Innovade, but has sided with Celestial Being, and a number of other Innovades were shown participating in ordinary life worldwide in the final episode of season 2.

Ribbons Almark is the main antagonist of the series, acting through Alejandro Corner in the first season before abandoning him. Seeing himself to be godlike, Ribbons' main goal throughout the series has been to twist Aeolia's plan to suit his own agenda of ruling humanity. He's extremely arrogant, considers himself superior to both humans and Innovators. Using the A-Laws from behind the scenes, Ribbons watches the battles unfold from the comfort of his lair. The novels and Gundam 00 S2 Ep 14 had revealed that Ribbons is the pilot of 0 Gundam. During an intervention mission in the Kurdish Republic, he was supposed to kill all the combatants in there; however, upon seeing the awed young Soran Ibrahim, Ribbons perceives the boy's look to be one of utter admiration and worship, and lets him live. Afterwards, he went and tampered with Veda's files in order to make Soran into Setsuna. He would later comment that this was a "momentary impulse... but also a sort of mercy." During a face-to-face meeting with Setsuna, Ribbons reveals his part in his entry into Celestial Being by tampering Veda's files while attempting take the 00 Raiser from him. After having Regene killed, Ribbons then proceeds to begin the final phase of his plan. However, after killing Tieria, Ribbons learns too late that Tieria merged his mind with Veda and as a result, loses control of Veda. Refusing to let his plan die, Ribbons reveals himself in the Reborns Gundam to fight Setsuna's 00 Gundam before taking one of its GN drives to re-power his 0 Gundam to battle Setsuna in the rebuilt Exia R2 in a heated battle until the 0 Gundam is destroyed. Ribbons Almark is voiced by Tōru Furuya (using a pseudonym Noboru Sōgetsu) in Japanese and Michael Adamthwaite in English.

Regene Regetta is an Innovator who is the genetic twin of Tieria Erde.[e 21] Although he works closely with Ribbons Almark, the two do not always see eye to eye (in part because of Ribbons' ego). As a result, Regene often acts of his own will to complete the plan Aeolia intended, from meeting with Tieria to leaking Veda's location to Wang Liu Mei.[e 22] However, Ribbons was a step ahead of Regene and had Ali Al-Saachez kill him when he attempted to kill Ribbons.[e 12] However, Regene's consciousness lived long enough to see Tieria use the codes he gave him in their meeting to lock Ribbons out of Veda. Regene Regetta is voiced by Romi Paku in Japanese and Nicole Oliver in English.

Revive Revival is an Innovator and the genetic twin of Anew Returner. Revive joins the A-Laws to combat the Gundams and pilots the Gadessa. Like Mr. Bushido, Revive holds a special license that allows him to act independently. However he agrees to follow Kati Mannequin's battle strategies. Later Revive allows himself to be captured by Celestial Being in order to steal the 00 Gundam and 0 Raiser with Anew's aid, but the attempt is thwarted. Revive is killed by Lyle Dylandy during the climatic battle at the end of the second series when the Cherudim Gundam targets the Gadessa's cockpit. Revive Revival is voiced by Mitsuki Saiga in Japanese and Cathy Weseluck in English.

Hiling Care[3] is an Innovator and the genetic twin of Ribbons Almark, expressing a fondness for him and bearing a grudge against anyone else he has a fancy for. Hiling also frequently teases her comrades. Joining Revive Revival with the A-Laws, also with a special license that allows her to act independently, Hiling is eager to battle with the Celestial Being and the Gundams. Hiling pilots a Gadessa and later a Garazzo in several operations against the Ptolemaios II. She is later ordered by Ribbons to retreat from A-Laws to help in defending Veda. In the final battles, she is brutally killed by the returned Hallelujah/Allelujah super-soldier, crying out to Ribbons to save her as she dies. Hiling Care is voiced by Miyuki Kawasho in Japanese and Brenna O'Brien in English.

Bring Stabity is an Innovator who is assigned to the A-Laws in order to combat the Gundams, considerably more stoic than his fellow Innovators. While Bring is able to overpower the 00 Gundam with the Garazzo in a display of force,[e 23] he is later defeated during the A-Laws' assault on Celestial Beings's L3 base when the 00 Raiser is formed during the battle.[e 24] Later, he and Revive are given orders to destroy the 00 Gundam. Bring is killed when he joins the attacking of the Ptolemaios II on Earth, fighting Tieria Erde whom he attempts to reason with (arguing that Tieria should join the other Innovators because he was one of them, to which Tieria replies by saying he isn't and that he is human) before his opponent reveals the Seraphim Gundam for the first time.[e 25] Four months after, Ribbons reveals the creation of a massive army of Divine and Bring clones. Bring Stabity is voiced by Ryōtarō Okiayu in Japanese and Brian Dobson in English.

Divine Nova is Bring Stabity's genetic twin and makes his first appearance piloting the prototype mobile armor Empress after Celestial Being successfully destroys Memento Mori.[e 25] After forcing the Ptolemaios II back into Earth's atmosphere, he later takes part in an assault on the Ptolemaios II which nearly succeeds until a coup d'état forces the A-Laws to withdraw.[e 26] Divine is killed by Setsuna F Seiei in the 00 Raiser while defending the second Memento Mori station.[e 27] Four months after, Ribbons reveals the creation of a massive army of Divine and Bring clones. Divine Nova is voiced by Ryōtarō Okiayu in Japanese and Brian Dobson in English.

Anew Returner is Revive's genetic twin who serves her group as a sleeper agent in the guise of mechanic who Liu Mei scouted after the activation of the 00 Gundam and assisting with development of the 0 Raiser and GN Archer support vehicles. When the Ptolemaios II arrives at Celestial Being's L3base and on Ian's suggestion, she joins the crew as the pilot and resident medic.[e 23] Over time, Anew develops a romantic relationship with Gundam Meister Lyle Dylandy.[e 22] Since joining the Ptolemaios II crew, Anew unknowingly served as a means for the Innovators to locate Celestial Being everywhere they go. It was only when Revive is captured that Anew's memories are restored, betraying Celestial Being and disabling the Ptolemaios II.[e 6] However her attempt to steal the 00 Gundam is thwarted and she escapes along with Revive. Anew participates in the next operation to capture the 00 Gundam and confronts Lyle during the battle. But when Lyle convinces Anew to return to him and Anew is about to return to him, Ribbons takes control of her and she is subsequently shot down by Setsuna when she is about to kill Lyle. The 00 Raiser's Trans-Am allows the two to share a brief moment together, confirming their feelings for each other before dying.[e 28] Despite her death, she briefly reappears in episode 25 during the inauguration of the new president of the Earth Sphere Federation. Anew Returner is voiced by Ryoko Shiraishi in Japanese and Lalainia Lindbjerg in English.

A Mobile Suit Squad Captain and the pilot of the GNMA-Y0002V Gadelaza, Descartes was a former member of the AEU before transferring into ESF Forces and is the second human to have become a true Innovator. After his transformation, Descartes has fully embraced being an Innovator and shows his superiority towards other people of his might in combat, although he has shown to be an arrogant and egotistical person. His quantum brainwaves enhance his natural piloting abilities, allowing him to maximize the performance of his mobile unit. He is also capable of fighting huge numbers of enemies using the Gadelaza's built-in weaponry along with controlling a massive number of GN Fangs, hinting that his capabilities are quite extraordinary for him to be able to actively pilot the Gadelaza whilst utilizing that many remote weapons. Similar to Setsuna F. Seiei, Descartes' Innovator abilities have yet to be fully defined, and most of his abilities are merely based on observation and speculation.

Despite being officially acknowledged by the Earth Sphere Federation, Descartes is being used to find other people with similar abilities. In the Gundam 00 movie, once the activities of the ELS are realized, Descartes begins developing headaches; the ESF soon notice an entire ELS armada emerging from Jupiter's red spot and set to arrive at Earth within 95 days. Descartes sorties against the enemy in an attempt to figure out their intentions and attempt to lure them away from Earth with his QBWs. However, when he deploys his fangs, some are assimilated, and feels the same mental assault suffered by Setsuna. His Gadelaza is assimilated by a gigantic ELS, and Descartes is killed in the process. Descartes Shaman is voiced by Ryo Katsuji in Japanese and Ryan Luhning in English.

An astrophysicist who works for the ESF, Mehna Carmine helps to solve the mysteries and investigate the ELS. It is also hinted that she has a relationship with Billy Katagiri. At one point in time, an ancestor of Mehna donated a DNA sample to the Corner family, which was later used by Alejandro to create the Trinity Siblings. While the Trinity siblings are a result of a combination of this DNA sample and genetic material from Ribbons, Mehna herself is a natural born human. Having proven herself to be highly intelligent, Mehna's similar appearance, as well as her impulsive and playful personality, to Nena Trinity are coincidental developments. While she does indeed show a jealous streak, it is never shown if she is capable of such callous acts that the Gundam Meister was. Mehna Carmine is voiced by Rie Kugimiya in Japanese and Nicole Bouma in English.

ELS

An unknown alien race, the ELS (Extraterrestrial Living-metal Shape-shifter) is a race of techno-organic sentient aliens that have the unique abilities to infect and assimilate nearly all life and technology. It is revealed their homeworld was destroyed by the Red Dwarf Star and set off to find another world to live. The ELS appear as a silver metallic organisms that can take solid or liquid-like forms. The ELS has no true form as they are capable of taking any shape or size relative to their mass; they can combine or separate from one another to increase or decrease its mass as needed. While not an aggressive race, their ways of learning and understanding their environment is based on assimilation of all things — being one with what they don't know allows them to understand. When faced with an opponent or something they cannot comprehend, assimilation occurs to convert the target of interest into an ELS.

When confronted with unknown organic lifeforms and/or technologies, the ELS assimilates the target like an aggressive virus. Its rapid adaptability and versatility allows it to take hold of technology in a matter of seconds and organic matter in a matter of minutes. However, for organics, it can have detrimental effects to those not completely assimilated, such as causing brain damage and various biological instabilities due to their invasive nature to their condition. While their complete nature is not understood, they can generate a noise signal for communication, initially their basic original physical form before assimilation is in a missile like shape, utilize quantum brainwave frequencies, make copies of what they have assimilated, and have their own GN-Tech and unique GN Particles, which are purple in colour. However, it is not clear whether it due to their own development and evolution or from copying Celestial Being's technology. In the epilogue, the ELS coexist with humanity.

Marina Ismail is the First Princess of Azadistan, which is struggling economically due to the UN's embargo on oil exports.[e 14] She is politically inexperienced and comes from an ordinary household, but accepted the position of Princess of Azadistan when Parliament chose her based on her lineage. She first encounters Setsuna F Seiei during her diplomatic mission to seek economic aid and access to the solar energy pipelines. After learning that Setsuna was one of Celestial Being's Gundam Meisters, she slowly develops a concern for his well-being. Conversely, Marina becomes an influencing figure in Setsuna's life; she appears in one of his dreams, telling him it is okay for him to stop fighting. At the very end of the first series, Marina reads a letter from Setsuna about his search for answers and that though the two follow separate paths, they share the same goal of ending war.[e 29]

During the second series, Marina is arrested by the Federation because of her perceived connection with Setsuna in the first series.[e 30] Setsuna rescues Marina during Celestial Being's operation to free Allelujah Haptism and brought on board the Ptolemaios II.[e 31] After witnessing Azadistan in flames because of an attack by Ali Al-Saachez, she is left in the care of her former adviser, Shirin Bakhtiar, who is now a member of the anti-government group Katharon.[e 4] However, Marina refuses to fight. Instead, she tends to the children orphaned by the conflict and uses their wishes as the basis for a song. In the epilogue, she is seen leading a rebuilt Azadistan.[e 25] Marina Ismail is voiced by Ayumi Tsunematsu in Japanese and Paula Lindberg in English.

In the first season, Shirin Bakhtiar serves as Marina Ismail's advisor and confidant. Shirin shows a great deal of political knowledge, however, much of her advice tends to be biting.[e 14] By the second season, Shirin has left Marina to join the anti-Federation group Katharon where she is Klaus Grad's sub-commander.[e 30] After Azadistan is attacked by Ali Al Saachez, Shirin comforts a grieving Marina.[e 4] Shirin tells Marina the only way to rebuild Azadistan is to destroy the Federation and that it is her duty to fight as its princess. However, Marina says that she doesn't see how fighting will resolve anything which Shirin replies by saying she doesn't mind if Marina chooses not to fight, but she vows to continue fighting for her homeland. In the epilogue, Shirin is seen as a politician for the new Earth Sphere Federation. Shirin Bakhtiar is voiced by Michiko Neya in Japanese and Ellen Kennedy in English.

Appearing in the second series, Klaus Grado is a top commander of the anti-government organization Katharon, which opposes the Earth Sphere Federation and its elite squad A-Laws. When Katharon member Lyle Dylandy joins Celestial Being as the new Lockon Stratos, Klaus begins a regular correspondence with Lyle about Celestial Being's activities. After helping the crew of the Ptolemaios II escape from an A-Law ambush,[e 32] Klaus proposes an allegiance, however, the proposal is rejected by Sumeragi Lee Noriega and Setsuna F Seiei.[e 33] Despite the rejection, Klaus continues to offer support to Celestial Being whenever possible. Four months after the collapse of the African orbital elevator, Katharon's Earth forces are nearly wiped out. Klaus decides to head to space, given hope by the global spread of the song written and sung by Marina Ismail and the children. In the epilogue, Klaus became a politician for the Earth Sphere Federation along with Shirin.[e 7] Klaus Grad is voiced by Tokuyoshi Kawashima in Japanese and Alistair Abell in English.

In the first series, Louise Halevy is Saji Crossroad's girlfriend and classmate. She becomes an acquaintance of Setsuna F Seiei when the latter becomes Saji's neighbour. While Louise is attending her cousin's wedding, Gundam Throne Meister Nena Trinity attacks the wedding party killing Louise's entire family and causing Louise to lose her left hand, which is unable to be regenerated due to the red GN particles. After the attack, broken mentally, Louise breaks off her relationship with Saji so that he can be free to pursue his dream of working in space.

In the second series, after receiving an artificial limb, Louise becomes a member of the A-Laws after Regene Regetta escorts her from a hospital to meet with Ribbons Almark, who channels her intent for revenge and world peace and attempts to make her the first purebreed Innovator with pills that enhance her physical capabilities despite the side-effect of causing slow bodily deterioriation. She learns of Setsuna's connection with Celestial Being after meeting him at a party held by Ribbons. During the A-Laws' attack on Celestial Being's asteroid base, she discovers that Saji is helping Celestial Being and assumes that he has been with Celestial Being all along. Her hatred for Celestial Being grows, first after the reported death of Soma Peries and later when her commanding officer Barack Zinin is killed in action. After the collapse of the Africa tower, she learns that Andrei Smirnov killed his own father. Shocked by the revelation, she wonders if she could ever do the same to Saji. Louise almost crosses that barrier as she gains the mobile armor Regnant from Ribbons which she uses to kill Nena, falling under Ribbons's influence after her mental breakdown. During the final battle when she clashes with him until she sees him wearing the engagement ring he gave her and she faints upon being overwhelmed by her memories of them together. At the season's epilogue and in the movie, Louise is once again in a relationship with Saji but is plagued by chronic PTSD. Louise Halevy is voiced by Chiwa Saitō in Japanese and Kelly Sheridan in English.

Originally a civilian and a senior high school student studying aerospace engineering, Saji is also Setsuna F Seiei's neighbour at Setsuna's residence in Japan. Orphaned prior to the start of the series, Saji was cared for by his sister Kinue. A gentle person with a submissive personality, he is often pushed around by his overbearing girlfriend Louise Halevy and continued to make ends meet with delivery job at a pizza parlor. Despite his unaggressive nature, Saji has been caught up in the wake of the Gundams' actions, with Louise suffering and Kinue dead. As a result, Saji has developed a deep hatred for the Gundams, blaming them for the loss of his loved ones as he leaves for space to live his dream as an engineer. In the second season, after being arrested under false charges of Katharon involvement, Saji is saved by Setsuna and learns his identity as a Gundam Meister. While on the Ptolemaios II, he reluctantly becomes a part of the crew and learns the truth behind the events years ago, allowing him to abandon his grudge and eventually understanding Celestial Being. When he becomes the pilot of the GNR-010 0 Raiser, Saji learns of Louise being in the A-Laws and chooses to fight to save her. By the end of the series, Saji leaves Celestial Being and watches over Louise while she is recovering at a hospital, where they talk about humanity's future. Saji Crossroad is voiced by Miyu Irino in Japanese and Gabe Khouth in English.

Saji's older sister. Pursues Celestial Being during the course of working in the media. Dislikes Louise. She and her brother Saji were orphaned prior to the start of the series.[e 34] Kinue seemed obsessed over Aeolia Schenberg, believing that Celestial Being had motives other than ending warfare and that researching Schenberg is the key to discovering those motives. In episode 20, desperate for a lead, she interviews Ali Al-Saachez in his car. He gives her significantly more information than she expects, shocking Kinue before she is fatally wounded by Ali and left to die in an alleyway. Kinue Crossroad is voiced by Aya Endo in Japanese and Anna Cummer in English.

Gundam Throne Meisters/Team Trinity

Although Trinity's past and origins remain a mystery in the show itself, the official Mobile Suit Gundam 00 novels state that the three siblings were created by Ribbons Almark, who used parts of his own DNA to engineer human beings with several Innovator-like traits.[4] As a result, they are able to perform otherwise impossible tasks such as interfacing with Veda and using quantum brainwaves. But unlike the Innovades, the Trinity siblings have significantly less androgynous appearances.

Oldest of the three siblings, Johann pilots the Gundam Throne Eins. Undertaking the mission to eradicate the world's strife, he began armed interventions alongside Michael and Nena. He is a calm person who faithfully handles his given mission while he commands his problematic brother and sister. His rational and cool-headed demeanor provides a subtle contrast to his fiery and stubborn younger siblings. Also unlike his younger siblings, Johann does not take lives that are not involved in their mission. An excellent marksman, he handles the firing of the GN Mega Launcher equipped on the Gundam Throne Eins. Johann is killed by Ali Al-Saachez after Al-Saachez kills Michael and steals the Throne Zwei. Johann is voiced by Katsuyuki Konishi in Japanese and Michael Daingerfield in English.

An impulsive young man, Michael immediately bares his fangs at people who oppose him, brandishing his trademark knife when feeling enraged or intimidated. He is also very rude to the first four Gundam Meisters upon their first meeting, although he does comment that Tieria Erde would be "kinda hot" if he were a girl. Similar to his personality, he favors brutal tactics for mobile suit combat and specializes in attacks with the Gundam Throne Zwei's all-range weapon, the GN Fangs. Though he feels somewhat protective over his younger sister, Nena, he frequently complains about having to comply to orders from his brother, Johann. Michael is killed by Ali Al-Saachez who then goes on to steal Michael's Throne Zwei. Michael is voiced by Daisuke Namikawa in Japanese and Andrew Toth in English.

Nena Trinity is the youngest of the Trinity siblings and pilot of the Gundam Throne Drei. Nena presents herself as being a cheerful and flirtatious young girl, however she is selfish and callous in battle.[5] Between two of Team Trinity's missions, Nena fires upon an unsuspecting wedding party, killing Louise Halevy's entire family, out of frustration that others are having fun while she is overworked.[e 35] After witnessing the deaths of Johann and Michael at the hands of Ali Al-Saachez, Nena is saved by Setsuna's timely intervention, and leaves in her Gundam while mourning the loss of her brothers.[e 3]

In the second series, intent on surviving, Nena works directly under Wang Liu Mei. Piloting the Riian, she is often sent out on stealth and reconnaissance missions to gather information on the activities of groups such as Katharon and the A-Laws. But because of Liu Mei's contacts with the Innovators and Ali Al-Saachez, Nena begins to question Liu Mei's motivations as she secretly helps the crew of the Ptolemaios II. She finally betrays Liu Mei by attacking her ship.[e 6] Though Liu Mei and Hong Long survive the assault, Nena tracks them down and shoots Hong Long in the head and later kills Liu Mei as she tries to escape, revealing she always hated her. While she intended to eventually betray the Innovators and avenge her brothers when she got a chance, Ribbons Almark had already arranged her to be dealt with by Louise in the Regnant, immediately attacking her as a result. After disabling the Throne Drei, Louise kills Nena without mercy to avenge her parents.[e 7] Nena is voiced by Rie Kugimiya in Japanese and Nicole Bouma in English.

Ruido Resonance is one of the four Gundam Meisters employed by Celestial Being in the period in which 00P is set. Designated pilot of the Gundam Astraea at Krung Thep. A skilled mechanic, and a senior member to Chall Acustica as of her inception as Meister. He later married Marlene Vlady and is the father of Feldt Grace. He and Marlene were killed in an accident involving Gundam Plutone, an incident which also caused Chall to be permanently scarred.

Marlene Vlady is one of the four Gundam Meisters employed by Celestial Being in the period in which 00P is set. A criminal forced by Celestial Being to serve as a Meister of a prototype Gundam unit at Krung Thep. As she does not support the organization's ideology, a remotely detonable explosive has been strapped around her neck to keep her under control. Extremely skilled at piloting. Partner to Chall Acustica as of her inception as Meister. She is the mother of Feldt Grace.

Chall Acustica is one of the four Gundam Meisters employed by Celestial Being in the period in which 00P is set. A member of Celestial Being and the designated Meister of a prototype Gundam unit. Selected for recruitment by Veda on the basis of her academic performance and her ranking in Power Loader competitions. Ruido Resonance believes that other qualities may have influenced Veda's arbitration. In Mobile Suit Gundam 00F, she is the commanding officer of Fereshte, having ceased active service as a Meister after an incident that scarred her face and prematurely whitened her hair. Following the completion of the Gundams, she obtained permission from Veda to set up the branch of Celestial Being known as Fereshte. She is stated to have some past relationship with the Gundam Plutone.

Gundam Meister 874 is one of the four Gundam Meisters employed by Celestial Being in the period in which 00P is set. Designated pilot of the Gundam Sadalsuud. Though Meisters are typically referred to by codename, 874 is designated only by number. For unspecified reasons, she does not appear before the other members of the organization. Physically, she looks younger than 10, but her eyes seem far older.

Grave Violento is a third generation meister and agent for Celestial Being; he is eventually revealed to be a combat type Innovade. Meister of GN-XXX Gundam Rasiel. Despite his designation as a meister, Grave spends more time acting as an agent to acquire information on military operations in preparation for Celestial Being's debut and protecting the organization by manipulating intelligence to ensure Celestial Being remains a secret it begins its armed interventions. Because of his role as an agent, he is also responsible for locating potential Gundam Meisters for the fourth generation Gundams; Grave personally recruits Neil Dylandy and Allelujah Haptism as Meisters. Despite diligently following the orders of Veda, Grave gradually becomes suspicious of Veda's directives and eventually opposes and chooses not to complete them.

Hixar Fermi is the pilot of GN Sefer. His jovial personality allows him to talk freely with almost anyone, even when meeting them for the first time. Hixar enjoys making others laugh, though has considerable trouble doing so with the serious Grave and dark-mannered Chall. Several years later, he appears in 00F as a Gundam Meister on orders from Veda to follow Fon Spaak, who has been working independently from Fereshte. While Hixar appears to be the same man from 00P, his personality is markedly different and he is shown to have a remotely detonatable explosive strapped around his neck. Hixar is eventually revealed to be an intelligence-gathering Innovade, recalled to Veda after his supposed death, for a new mission. His loyalties, and that of Hayana, eventually shift away from Veda to Celestial Being.

Highly skilled and proud, Delphine Bedelia is a test pilot from the Next Generation Development Technical Laboratory of the Human Reform League and serves as the Tieren Kyitwo mobile suit's rear seat pilot. Though she initially dislikes being partnered with Leonard and regards him with little respect, Delphine ends up wanting to protect him. After she and Leonard become eyewitnesses of the Gundams, they are designated by Veda as the second of the primary targets to be eliminated when Grave is assigned to eliminate those aware of Celestial Being's existence; after they are spared, they choose to join Celestial Being in order to find Allelujah, whom they have come to regard as a comrade. In Gundam 00I 2314, Delphine joins the reorganized Fereshte under the code name Dell Erda(デル・エルダ,Deru Eruda?) and participates in the development and retrieval of the GN Drives at Jupiter with Hayana.

The front seat pilot of the Tieren Kyitwo sent from the Super Soldier Special Duty Organization to become a test pilot, despite only being seven years old and lacking any apparent ability as a supersoldier save a susceptibility to the emission of quantum brainwaves from other supersoldiers. Unemotional and rarely anxious, he is kindhearted and comes to regard Delphine as an important person who must be protected. When Grave is assigned to eliminate eyewitnesses to the Gundams and those aware of Celestial Being's existence, Leonard and Delphine are second among the designated targets; when Grave spares them, they elect to find Allelujah, whom they have come to regard as a comrade, and join Celestial Being. In Gundam 00I 2314, Leonard has been designated as a Gundam Meister for Fereshte under the code name Leo Sieg(レオ・ジーク,Reo Jiiku?) and charged with protecting Delphine and Hayana as they retrieve the GN Drives from Jupiter.

A protagonist in the sidestory Mobile Suit Gundam 00F. A criminal forced by Celestial Being to serve as a Gundam Meister at Fereshte. As he does not support the organization's ideology, a remotely detonatable explosive has been strapped about his neck to keep him under control. Normally handcuffed, except when piloting. In Gundam 00F Chapter 03, Fon Spaak seems to recognize Ali when pursuing Ali with his Albuhool Type F, dismissing Ali as a relic of the past Solar Wars. In Gundam 00F Chapter 04, the remotely detonatable bomb which causes blood to ooze out is activated by Trinity when Fon attempted to stop them from taking away 0 Gundam and its GN Drive.

Fon's true name is Robert Stad Jr as revealed by Nena Trinity in Gundam 00F Chapter 05. His parents were involved in mining materials for colony construction, and the harsh environment led him to becoming an anti-Union terrorist. In a later chapter of the Gundam 00F manga, Fereshte sends Fon to recover the GN Drives from the Kyrios and Virtue after Celestial Being's battle with the UN Army. Though Fon retrieves the Kyrios' ejected GN Drive, he allows Allelujah to be captured rather than rescue him and leaves Tieria in the wreckage of the Virtue after finding that its GN Drive has been ejected as well, despite Meister 874's request to rescue Tieria.

In addition to appearing in Gundam 00F, Fon appears in Gundam 00P, encountering Grave Violento when Fon was a soldier for the AEU during the Solar Wars; during this time, he was already known as "Fon Spaak". It is also revealed that he was also involved with Ali Al-Saachez as a child soldier, much like Setsuna F Seiei. When Grave is assigned to eliminate eyewitnesses to the Gundams and those who have become aware of Celestial Being's existence, Fon is the first target named by Veda.

Once a candidate Gundam Meister, but because he is inferior to Setsuna and the current Meisters, he was removed and is now a pilot for Fereshte. He's a strong believer of Aeolia Schenberg's words of eliminating wars all over the Earth. Eco does not get along with Fon, believing that Fon is unsuited to be a member of Celestial Being because of his status as a criminal. He is usually the comic relief in 00F, having a tendency to overreact when Fon either points out something (usually obvious) to him or annoys him with his devil-may-care disposition.

A disciple of CB mechanic Ian Vashti. Has a good mechanic sense and maintains the modified prototype Gundams used by Fereshte. Though she is unemotional and seldom speaks, she does have another side to her and considers herself to be quite feminine. Good friends with Hanayo and is frequently seen with Hanayo. Following the dissolution of Fereshte, Sherilyn devotes herself to helping develop the GN Condenser to match the levels of output achieved by the GN Drives.

A manmade AI that is of the same model as Lockon's Haro. Its ear-like flaps gives it a cat-like look. Partners with Fon in missions and provide support for him in the MS. It also acts as a supervisor and unlocks Fon's handcuffs on missions and probably locks them back after missions. Hanayo is able to set up a datalink with Lockon's Haro through Veda. It is confirmed that Meister 874 is inside Hanayo. As shown in Gundam 00F file No.05, Hanayo/Meister 874 can take control over Gundam Plutone.

A girl who obeys Hixar Fermi, Hayana possesses high physical capacities most would not imagine from her appearance. Registered as a Gundam Meister in Veda, she is capable of taking control of a Gundam remotely. Hayana is considered Hanayo's "sister" and resembles her, but views Hanayo with hatred and attempts to eliminate her by destroying Hanayo's terminal.

He studies the developmental history of MS. He was initially studying political history, but after experiencing the revolution brought by Celestial Being when he was 30 years old and coincidentally seeing the Avalanche Exia in action, he switched his study to MS development history. An original character for sidestory, Mobile Suit Gundam 00V. Apart from that, he was also able to see the Dynames Torpedo and Shell Flag in action.

A female test pilot of the UN. She is also an old acquaintance of Robert Spacey. She was engaged by the Gundam Exia in an American military base on Okinawa when she was inspecting the Shell Flag's features. She proved herself to be a great pilot as she was able to survive the battle uninjured.

An ace pilot of the Earth Sphere Federation Army with an unconventional style of piloting solar furnace equipped mobile suits. He is worshipped as a hero known as the "Steel Cowboy", but also hated as the "Devil of Unification". Despite being well-regarded, his piloting ability cannot measure up to the Gundam Meisters and he has poor analytical skills.

An Innovade with the same pattern as Ribbons Almark: type 0026. He is physically 18 years old. As an Innovade, Leif has the ability to distinguish humans from Innovades and he has been charged with finding and educating other qualified Innovades.

An Innovade who has been working as a doctor and was previously affiliated with Doctors without Borders. Though he is 40 years old, his nature as an Innovade prevents him from aging like humans and he physically appears to be only 20 years old. He has lived in human society for over twenty years, despite Veda's average limit of 10 years before recalling Innovades to have their memories wiped and replaced, likely because of his renown as a doctor. Dr. Telicyra is responsible for awakening Leif as an Innovade.

An enigmatic Innovade who has lived in human society for over 130 years as a result of his information link to Veda being severed, though he is still monitored. At one point, he married and raised a family. Over the past 100 years he has killed other Innovades for reasons unknown, but appears to suffer emotionally when he kills. Since many of his victims have the same outward appearance, Veda intervened to hide his mass murders and Lars has never been caught. His left eye is artificial.

An eight-year-old Innovade who is dressed like a young girl, despite identifying as a male. Bryn appears to only be able to communicate through his powerful quantum brain waves; when he is captured and imprisoned in the same Earth Federation facility as Allelujah Haptism, he is able to "speak" to Hallelujah through their quantum brain waves. During his imprisonment, Bryn's blood is drained by Dr. Clay Lihichyte, the doctor who created the Trinity siblings, and rendered physically immobile as a result.

An Innovade with the same base sequence as Telicyra, but her sex has been set as female. As an Innovade, she is capable of awakening other Innovades. She is currently acting as a member of Katharon alongside Hermiya. Both she and Telicyra apparently want to conceal they are Innovades of the same type, though they eventually refer to each other as brother and sister.

An Innovade who presumably has the same base sequence as Hanayo (Gundam Meister 874) and Hayana, since her appearance to them is very similar. Unlike Hanayo and Hayana, she appears cheerful and has been seen at a Katharon base. She has the ability to erase and reset Innovades. Like her comrades, she has been tasked by Veda to be an observer to perfect Aeolia Schenberg's plan.

A Innovade with the same base pattern as Ribbons Almark, the pilot of the 1 Gundam and a rogue agent of Celestial Being with access to Veda. Like Ribbons, he can transfer himself into another body if his current one is destroyed, though his transfers take more time. In Gundam 00P, Beside uses the ability to transfer his mind to take control of Hixar Fermi and attack Grave Violento. However, when Grave defeats Beside, he is unable to initiate a complete transfer into a new body; the partial transfer results in the awakening of Leif Recitativo. Because of their shared consciousness, Beside haunts and tries to take control of Leif in order to further his own goals until Telicyra is able to wipe Beside from Leif's mind.
